Fig 1: Flow cytometric profiling of cells in the peritoneal cavity reveals an influx of T lymphocytes 6–8 days post-infection with OMP in C57BL/6 animals. Cell number (blue line; left y-axis) and percentage (red line; right y-axis) of (A) B1 B cells (B220lo CD11b+ CD5−), (B) B2 B cells (B220hi CD11b− CD5−), (C) CD4+ T lymphocytes (TCRβ+CD4+), and (D) CD8+ T lymphocytes (TCRβ+CD8+) following inoculation with 106 OMP. Data from three independent infections (n = 2) with average and SEM displayed. Statistics were acquired through unpaired Student t-tests relative to day 0 samples with *P < 0.05 and **P < 0.01. Blue and red asterisks, significance of cell number and percentage data, respectively.
